Intake Manifold Shootout

Is it just me, or is there some reason that we never see a meaningful comparison test of the intake manifolds offered to rodders. It is apparent that everyone has their own preferences, but can that be attributed to a plain old emotional attachment?

I am playing with the software dyno that Comp makes available, and in the Intake Manifold section, it speaks of low-medium & hi flow duel plane manifolds.

Nothing by any manufacturer gives me a clue as to how they rate the airflow of their products. Worse than that, how does one compare Brand A with Brand B?

How does a Weiland Stealth compare to an Edlebrock Performer?

Does an Edlebrock Performer Pro trump a Weiland Stealth Air Strike?

Curious minds want to know these things!

Help!

Manifolds

Just Google"manifold shootout" there are several that will come up, pay attention to the RPM and torque range and pick your cam to match and you'll be OK.

There must not be anything out there for the SBC guys.

I can find stuff for Fords and Mopars, but nothing for the SBC.

I can find articles for Volkswagons and the Acura, but no SBC stuff.

I would tend to believe that surly someone besides myself has wondered about this stuff. Is it possible that the difference between products does not amount to a hill of beans? Is it possible that no matter what brand you choose, they are all the same?

Google did not come to the rescue, that is why I am posting my question here to you guys.

I have also looked for a good manifold comparison. Normally they test 2-3 manifolds of the same brand. My guess would be that the major magazines wouldn't want to upset any of there advertisers by saying brand A or brand B sucks. Not many individuals would have the time or money to do a test like this.

You know, that was the slant I was thinking applied to this subject.

I cannot believe that for a part as basic as an intake manifold... a part that the companies have published claims of performance for... that no magazine or online reviewer would find this a subject of interest for their followers!

I guess we have to go by someone else's experience and then see if it applied to our own need.

Hot Rod magazine did one last year, I think. Cant remember what month. Basically it came out that bang for the buck on a street machine was the RPM Air Gap.

I thought that shootout would show up online,I have hundreds of Super Chevy and Chevrolet High Performance magazines and remember reading it,they tested 12 different intakes.The manifold that showed the most power and torque overall was a manifold that came out in the mid 70's, the Offenhauser Dial-a-Flow.This manifold had an open plenum and a set of 3 adapters that you could change the RPM range with so you could use it on the street or the track by changing adapters in the plenum,oddly enough it produced the highest results in the test without the adapters.Next best were the Weiand Stealth,Edelbrock RPM Air Gap,and the Offenhauser Port-O-Sonic.The reason you don't hear about the Offy intakes one of the oldest in the USA, is they just don't spend money on promos and advertising just good old American quality and workmanship is foremost with them.
